【Abstract】 The scheme design of extrusion die is directly dependent on the die graph, which is different from the one treated by general expert system. According to this, the paper introduces the expert system JCMES for the design of extrusion die. A method of reading the output files . DXF from AutoCAD is proposed during inputting the graphics of different plastic profiles and their corresponding dimensions by using the screen prompt. Some practicable algorithms for identifying these graphs are designed and the interactive design methods for implementing the expert system design of different profiles and die graphs are used. The system is programming with Visual Basic 3. 0.更多还原
